What happened
During its flight, a heavy bomber experienced simultaneous mechanical issues when both engine number one and engine number four ceased functioning. Following the loss of power in these two engines, the flight crew initiated an emergency bailout procedure. All 11 crew members successfully exited the aircraft before it impacted the terrain.
The aircraft subsequently descended into the ground, resulting in a crash located approximately 5 km north of Kaesŏng. While the impact resulted in the total destruction of the airframe, all personnel were recovered from the site and found to be alive.
Findings
- The loss of propulsion was caused by the failure of engine number one and engine number four during the flight phase.
